BB93's SLRR, as well as 2.3.0LE,
My system specs, Core i7, 720, AMD Mobility Radeon HD5650, 8GB ram, HP Pavilion DV7 laptop.
Problem is stuttering/frame rate issues. I have tried everything on its very lowest to everything maxed out, and there is hardly a difference.
My cousin has a Core i5 machine of round about the same vintage as the HP, with some mobile NVidia card with 512mb VRAM, the HP has 1GB VRAM, and the stutter, lag and general random FPS drops are nowhere to be seen on his machine. Copied one of my installs to his machine, and promptly won the ROC on 2.3.0, where on my machine it is unplayable. his framerate pegs at 80 and stays there, maxxed out. I've overclocked my GPU, tried lots of stuff, other games like COD bleck ops runs smooth like butter, on GTR2 with a full grid starting from dead last it pegs at 60fps and never budges, with everything maxxed out. Get a slight fps drop when I encounter smoke in GTR2, but other than that no problem.
